How Las Vegas grades restaurants

The Southern Nevada Health District grades on demerits, and here more is worse: roughly 0–10 demerits earns an A, 11–20 a B, and 21 or more a C. Serious problems can skip the ladder entirely — an imminent health hazard gets the permit suspended and the kitchen shut on the spot, which shows up as a closure rather than a letter. SNHD covers all of Clark County, so Henderson, North Las Vegas and the unincorporated Strip all run the same scheme. Cooked reads A as clean, B as mid, C or a closure as cooked.
